    摘要： A motor grader includes a blade between a front wheel and a rear wheel, the blade being attached to a swing circle which adjusts a blade angle. A control method performed in the motor grader includes obtaining current topography in front of the motor grader and adjusting the blade angle to an angle in accordance with the current topography by revolving the swing circle.

    摘要： A self-propelled off-road agricultural vehicle is provided with a hydraulic propel circuit protection system. The hydraulic propel circuit protection system reduces extreme pressure buildup from the motors when the pumps and/or motors are rapidly deactivated. The hydraulic propel circuit protection system may include a propel manifold with integral valving and an accumulator to protect a propel circuit of the self-propelled off-road agricultural vehicle. External relief valves which may be integrated into the propel manifold may limit the high pressure condition on the outlet of the motors to a level that prevents damage to the hydraulic motors and the accumulator provides supplemental flow and thus prevents the extremely low pressure condition from occurring at either side of the motors.

    摘要： A vehicle vacuum power system which insures sufficient vacuum power to operate a vacuum brake booster and a vacuum operated road speed control system. Because of the low vacuum, high flow rate needs of a cruise control system, the cruise control is connected directly to the engine manifold through a check valve. A small orifice from the vacuum pump in parallel with engine manifold vacuum provides sufficient vacuum for the cruise control when the manifold vacuum is not sufficient. The vacuum pump is in series with manifold vacuum and is operated in response to a pressure switch which allows the pump to run only when brake booster vacuum is low. Manifold vacuum is sufficient most of the time, but the orifice to the cruise control tends to cause a fast loss of brake booster vacuum, causing the vacuum pump to run when it is not actually needed. The vacuum regulator shuts off the flow through the orifice when it is not needed, considerably reducing the pump operational time. The regulator is a two-piece housing with a spring loaded diaphragm controlling a regulator port. Atmospheric pressure is on one side of the diaphragm and engine manifold vacuum is on the other.

    摘要翻译： 一种车辆真空动力系统，其确保足够的真空动力来操作真空制动助力器和真空操纵的道路速度控制系统。 由于巡航控制系统的低真空度，高流量需求，巡航控制通过止回阀直接连接到发动机歧管。 当真空泵与发动机歧管真空并联时，小孔口在歧管真空度不足时为巡航控制提供足够的真空。 真空泵与歧管真空串联，并且响应于压力开关而操作，只有当制动器增压器真空度低时才允许泵运行。 歧管真空大部分时间是足够的，但巡航控制的孔口往往会导致制动助力器真空度的快速下降，导致真空泵在实际不需要时运行。 当不需要时，真空调节器关闭通过孔口的流量，大大减少了泵的运行时间。 调节器是一个两件式外壳，带有弹簧加载的隔膜控制调节器端口。 大气压力在隔膜的一侧，发动机歧管真空在另一侧。

    摘要： An electrically operated vehicle provides a series of rotary members specially mounted to be partially exposed to external direct fluid currents and deflected fluid currents from a deflecting member. Each rotary member provides a series of substantially flat radial vanes circumferentially spaced in quadrature with the vanes of one rotating member angularly spaced with respect to the quadrature type vanes provided by an axially spaced rotary member. An axially spaced fluid conducting channel provides a vacuum at an axial end of a rotating member for reducing back pressure. An electrical control automatically responds to the differentially sensed electrical charges, within a pair of separate batteries for selectively connecting the battery with the lowest charge to the energy generating source and the battery with the greatest charge to energize an electrical motor driving the vehicle.

    摘要： A vehicle, especially a motor vehicle with two adjusting mechanisms which are actuated by an auxiliary force and which are of unequal rank as regards the maintenance of the operating safety; a control device is thereby provided in the line leading to the respective subordinate adjusting mechanism which interrupts a further supply of the auxiliary force when its characteristic magnitude reaches a predetermined value which is still sufficient for the completely satisfactory operation of the next higher ranking adjusting mechanism.

    摘要： Turning radius is calculated from steering angles of steering-wheels and articulation angles of respective frames, and the steering-wheels are automatically rotated faster than rear-wheels based on the turning radius, the revolution number of the rear-wheels, engine speed of an engine and a speed range of hydraulic motors, so that conventional trouble for manipulating operation lever etc. while turning a motor grader and skill-requiring work for adjusting the revolution number of the steering-wheels in accordance with the revolution number of the rear-wheels can be eliminated, thereby easily and accurately controlling the revolution number of the steering-wheels and securely preventing tight-corner braking phenomenon.
